IMPROVEMENT iN FGRCE-PUMPS.

Specification forming part of Letters Patent No. 130,626, dated August 20, 1872;'

To all 'whom it may concern:

Be it known that I, BENJAMIN BRUNDAGE, of Sumpter, in the county of Wayne, in the State of Michigan, have invented a new and useful Improvement in the Construction of Forcing-Pumps for raising water for any purpose; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in so arranging a single valve to vibrate in the bottom of the tube or cylinder C as to aid in raisin g the water promptly, and at the same time allow the water to fall through the open throat into the fountain, well, or reservoir as soon as the pumping ceases.

In the drawings, Figure 1 represents the pump properly put together for use. Fig. 2 represents a sectional view of the same, showing the position and shape of the various parts, not shown in Fig. l. Fig. 3 represents the position of the valve, with the frame on which it rests and in which it works; while Fig. 3a shows the frame, and Fig. 3" shows the valve, each separately.

In Fig. l, A is a lever, connecting and operating the piston-rods B and B. (l is the tube through which the waterV rises.4

ce through which the water enters the waterchamber; and E E E, the box inclosing the valve, chamber, Ste.

In Fig. 2, A, B and B', and G represent the same parts as in Fig.'1. F F show the waterchamber. K K show the frame and its open- D is the ori- The manner of constructing and operating the pump is as follows: ll being in place, as seen in Fig, and power being applied to the lever A, the piston B descends upon the water in t-he chamber F, forcing the valve to the opposite side of the bottom of the tube C, also closing the opening K by the wing ofthe valve, and causing'the water to rise in the tube, in the direction shown by the arrow. The valve is then in the position shown in Fig. The motion of the lever being reversed, the piston B descends, the valve is forced `to the opposite side of the tube, the opening K is closed, and the water again forced up the tube. W hen the workin g of the pump-lever ceases, whether the valve stands at either side the throat of the pump or in the middle, the water remaining in the tube 'immediately falls to the bottom, leaving the tube entirely clear, 'avoiding all danger from frost.

What I claim as my invention, and desire to secure by Letters Patent, is

The sliding valve H, arranged to operate substantially as shown and described.
